What does 'The wallet is busy' mean ?

Some tasks that you perform on the wallet can take a while, especially on large wallets. This includes importing and
exporting private keys and changing the password protection. To enable you to carry on working, MultiDoge runs these as
a background task. When a background task is running for a wallet, there is a '' shown
for the wallet in the ' Wallets'
panel. There is also a short note indicating what the wallet is busy with. This is typically: 'Synchronising. . .', 'Waiting. . .' etc.

When the task finishes the '' disappears.

You can only have one background task running for a particular wallet. When a background task is running, various
buttons and menu options are disabled. If you hover over one of these disabled buttons/ menu options there is a
tooltip like 'The wallet is busy with the task "Exporting private keys" '. The buttons and menu options are re-enabled
once the task has completed.

Each wallet has its own background task, so if one wallet is busy you can swop to another wallet and work with that
instead.
